摘要:

白云鄂博“白云岩”是世界上最大稀土矿床赋存母岩,也是铌、铁、钪和钍等大型超大矿床的载体。只要是“白云岩”就是铌、稀土等矿,“白云岩”的成因就是铌、稀土矿成因。所以,白云鄂博“白云岩”成为一颗灿烂的明珠,吸引国内外许多地质工作者考察和研究。对“白云岩”的成因提出不少完全不同看法。本文根据12矿区地质地球化学特征认为白云鄂博“白云岩”可能为岩浆碳酸岩。铌、稀土铁矿是与碳酸岩有关的矿床。

Baiyun obo “dolomite” is the world’s largest rare earth deposit occurrence parent rock. It is also the carrier of large-large deposits, such as niobium, iron, scandium, thorium, etc. As long as “dolomite” is Niobium-Rare Earth Mine. The genesis of the “dolomite” is also the genesis of Nb-REE ore. Therefore, Baiyun Obo “dolomite” becomes a bright pearl, attracting many domestic and foreign geologists investigate and study. For genesis of the “dolomite” in put forward a lot of completely different views. According to the geological and geochemical characteristics at 12 mining area, we think Baiyun Obo “dolomite” may be magma carbonatite. Nb-REE ore is mineral deposits associated with carbonate rock.
